Domain Inspector

Domain Inspector provides you with a dataset and visualizations that offer real-time visibility and historical reporting of domain-level metrics delivered by a Fastly service. It allows you to monitor traffic for a fully qualified domain name without requiring you to send log data to a third-party data collector.

Specifically, Domain Inspector aggregates response data (for example, requests, bandwidth, edge or origin response codes, and cache hit ratios) received by a specified service and presents that information for each domain either as visualizations in the web interface or as a JSON formatted data stream.
